Yeah, that's not how zero hour contracts work.

In practice zero hour contracts mean that if a company wants you to work you often need to work because if you don't they can simply not give you any more hours in future. I.e., the big difference between a zero hour contract and gig work is that in that the company controls the hours, not you.

And this isn't just because the companies are scummy, but for somewhat sensible operational reasons. Zero hour contracts are common in places like supermarkets because they allow companies to flex their staffing levels with, for example, seasonal demand (although there are other solutions to that problem that are better for employees!). On d day to day basis they might still need more shop floor workers on a busy Saturday than on a quiet Monday, so it means they need to be able to control the scheduling rather than workers controlling the scheduling to ensure they always have appropriate staffing levels. If you gave complete control to workers you'd regularly find you had too many people working at quiet times and too few at busy, and even if you put controls in place to avoid too many workers at a time, you'd never be able to guarantee that you'd have enough at busy times which wouldn't really be an acceptable outcome for anyone.

But going back to your point of misunderstanding: zero contracts are perhaps more like the worst aspects of gig employment married to the worst aspects of non-gig employment, which means that they operate quite differently to gig employment.
